Improvement in stump-extractors



UNITED STATES PATENT OFFICE.

IMPROVEM ENT IN STUMP-EXTRACTORS.

Specification forming part of Letters Patent No. 55,156, dated May 29,1866.

To all whom it may concern.:

Be it known that we, ALONZO PALMER and ROBERT GILLELAND, of Hudson,county of Lenawee, and State of Michigan, have invented certain new anduseful Improvements in Stump- EXtractors 5 and we do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the accompanying drawings and the letters otreference marked thereon.

In the drawings herewith attached and making a part of thisspecification, K represents the axle-tree, which is madeot heavy timber,having at each end two projecting pieces, between which are secured thewheels M M, for the purpose ot' propelling` the machine. These wheels Mare made in any ofthe ordinary7 forms in a substantial manner.

G represents the tongue, which extends from the under portion of theaxle-tree K forward a suitable distance to suit the required pury poses.

L is a horizontal bar which rests upon the tongue Gr. Extending backwardfrom each end ot' this bar L are beams A A, said beams being iirmlyattached to the projects which secure the wheels M and extend a slightdistance to the rear ofthe wheels, where the supports B B are attached.These supports are pieces ot' timber which act as legs to hold themachine in its place, and are pivoted to the beams A, being providedwith two or more holes to pivot them to the required height whenever itis necessary on account of the unevenness ot' the ground. When needed inan upright position to support the rear end of the machine, thesesupports B are held in their places by the braces C (J, (one on eachside of the machine.) These braces C are attached to the beams A, andare notched in the under part near the end to attach themselves to ascrew near the bottom ot' each of the supports. When the machine isdesired to be moved the supports can be thrown up and the wheels allowedmove the extractoreither backward or forward.

D Drepresents two stay's'made ot'heavy timber, resting upon the top ofaxle-tree K, and extending' to, with the ends resting upon, the bar L.These stays D D are set close together and upon the axle-tree, directlyabove the tongue G. Between the said stays is the lever E. This leverhas an adjustable clevis, F, at the rear end for the purposeshereinafter set forth. At the front end of the lever D is attached achain or rope, H, which extends from the lever end to and through apulley, I, which pulley is set within the tongue G, forward of the barL.

The lever E, heretofore described, has its fulcrum where it is securedbetween the stays D and directly over the axle-tree K, as seen at O inthe accompanying drawings.

The clevis F, at the rear end ot' the lever E, is provided with a seriesof holes to adjust it to the lever, and has a chain, a, or hooks at thelower extremity to encircle or attach it to the stump or other thingdesired to raise.

By the construction ot' this machine itwill be seen that the axle-treeis quite elevated above the beams A A to give the lever E more powerwhen desired to use the same.

The operation of this extractor is very simple. The tongue G is put uponthe ground, when horse or other power is applied to the rope or chain H.The lever E is raised to its full height, when the chain or hooks at theext-remity ot' the clevis F are fastened to the stump or thing requiredto be elevated, the supports B B being in an upriglit position, by thebraces C C. Power then being given, the rope or chain is drawn throughthe pulley I, carrying the lever E downward. It will readily'be seenthat the clevis, with chain or hooks, is brought upward, bringing by itsforce the stump or other thing from the earth. The braces C are thentaken from supports B and said supports thrown upward. The machine isthen drawn forward, carrying with it the incumbrance.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

The beams A A, supports B B, clevis F, stays D D, lever E, braces 'C O,pulley I, cord H, and tongue G, arranged in the manner substantially asand for the purposes herein set forth.

As evidence that we claim the foregoing we have hereunto set our handsin the presence of two witnesses.
